Initial CodeCraft: web-based coding harness for AI models

Rust backend (axum/tokio): agent loop with streaming, tools (fs, bash,
web_fetch, todo, ask_user, subagents, skills, craft snapshots/compare),
permissions with modes and rules, Anthropic + OpenAI-compatible providers,
MCP client (stdio/HTTP, elicitation), SQLite sessions, usage statistics,
compaction, commented TOML config editable via toml_edit.

React PWA: chat with live streaming, permission/question cards, modes
(build/plan/craft), settings for providers/models/prices/MCP/permissions,
raw config editor, statistics dashboard, i18n (en/de). Docker setup.
